Patients on chronic hemodialysis without obstructive coronary artery disease identified by
coronary angiography were randomly divided into the two groups: carnitine group and control
group. SPECT using FFA analogue, BMIPP, was performed before and one year after intravenous
administration of L-carnitine (1000 mg on every dialysis session). Control group received the
examination of BMIPP SPECT at the same time of the carnitine group. The effects of chronic
intravenous administration of L-carnitine on myocardial fatty acid metabolism were
investigated among this population.
